Not true. They are living their same day to day lives they have lived for thousands of years. It is natural for humans to search for answer in life. Who am I? What is this place? What do I do? Where do I go? When we don't have some kind of reliable method to help us discern, we imagine and believe. That's what other tribes have done. They made up their own religions to explain reality. That's what the Jews did as well as the Muslims. The birds did it and so did the Egyptians. The reason that these polytheistic and monotheistic beliefs have stopped sprouting up is because we are understanding and observing our reality. Our purpose as humans is to understand and comprehend. That's what separates us from animals.
